AI Technical Summary

Technical Problem

Existing sanitary napkins are prone to leakage during use due to loose adhesion or displacement of the wings to the underwear. In addition, leakage is also easily caused by insecure fixation at the front and back ends.

Method used

The sanitary napkin has Velcro hooks or silicone stickers on its wings and sides, with the Velcro hooks or silicone stickers in the second adhesive area being less than or equal to 10mm from the edge. A diversion layer and a leak-proof side are provided on the side away from the adhesive area to enhance the adhesive effect.

Benefits of technology

It effectively avoids the problems of displacement and leakage caused by poor adhesion between sanitary napkins and underwear, while improving the overall stiffness and anti-deformation ability of sanitary napkins and reducing the risk of leakage at the front and back.
